Abstract (en)
[origin: WO2022109727A1] In acoustic inspection, if a probe assembly fails to maintain a controlled lateral position relative to a structure such as a weld being inspected, as the probe assembly is translated along a scan axis, a nearby flaw could be missed or mistaken for an earlier-observed feature. Apparatus and techniques described herein can assist in tracking the lateral displacement of a probe assembly relative to a region of interest such as an edge or centerline of a weld. Such a technique can, for example, be used to gate the received ultrasonic data or to update a presentation to a user, such as for updating an overlay (e.g., a weld template) and ruler position in an S-scan or other image representation.
